Aldo the American Kestrel enjoyed a rain shower on Thursday morning. As he spread his wings to soak in the rain, his molting flight feathers were visible. He has short primary feathers growing on his left wing and new rectrices, or tail feathers. About two weeks ago, I found most of his tail feathers on the ground in his mew. Now, new feathers are starting to grow in and give the appearance of a diamond-shaped tail almost like a raven. Aldo’s tail will keep growing, though, until the feathers are all the same length.
